Paper production and publication manufacturing use paper stock types for various grades. The stock types primarily relate to the different purposes the paper serves in its end use. The most population will only encounter any stock types concurrently with an activity their works but will stumble upon many of the possible choices in time to time growth. 


Each stock type has a total capacity used and its base heaviness to delimit the paper’s values. Knowing a total capacity is essential in understanding why 30lb Newsprint is a more moderate grade of paper than 20lb Bond. 

What the public means when they discuss the heaviness of a page of paper or card is efficiently the density of that document of concurrence.

There are two agreements now in extensive use for paper weights:

  1. Europe and most parts of the globe that utilize ISO paper sizes, apart from a small group of nations still employing US paper sizes, use a measurement called grams per square meter (g/m2 or gsm), as specified by ISO 536.2. In those countries that adopt US paper sizes, the same measurement is used, and it is known as the basis weight, typically specified in pounds (lbs). The basis weight is the weight of a 500-page ream of the paper in its entirety.

They define grammage as grams per square meter (g/m2). Accordingly, the weight of a single page of A0 paper determines the grammage of that paper type, as ISO 216 describes the A0 size as having an area of 1 square meter. An A0 page of 80gsm paper will consider 80 grams, an A0 page of 100gsm paper will contemplate 100 grams, and so forth. 


Basis Weight 

Basis load is a much earlier practice for outlining the load of paper. Before the worldwide standardization of paper sizes by ISO 216 and attracting public attention in European nations, it was common in the UK, Europe, and North America, where it is still in use.

basis load

The basis weight is outlined as the burden of a ream of the complete paper in pounds (lb) (Note: # is frequently used as an abbreviation for pounds when referring to paper weights). They use the full paper sizes as the content utilized in the production process before cutting the paper to length. There are various types of full paper, including those used for work paper and sheets such as Bond Stock, Cover Stock, and Index Stock. When referring to the various types of paper in their full-cut sizes, the word “Stock” is often omitted.


Thus if you have a page of 20lb Bond Letter paper, it will be the regular width as 20lb Bond Legal, even though two together sheets will contemplate various amounts by way of the distinctness in length. However, a page of 28lb Bond Letter amount paper would not go along with a page of 28lb Cover Letter content paper as the full sizes for Bond and Cover are diverse. 

The newspaper has its own stock type, Newsprint, that measures 24” x 36” in complete breadth. This is much taller than the Bond and Cover full sizes, so the ultimate ordinary 30lb Newsprint is a much finer paper than a 20lb bond.
